MANcIIESTER, ENGLAND, A BRITISH COMPANY V GAS PRODUCER Application filed July 25, 1930, Serial No. 470,667, and in Great Britain August 1, 1929.

This invention relates to gas producers and comprises the improved combinations and arrangements of parts hereinafter described.

Referring to the accompanying sheets of explanatory drawings Figure 1 is a sectional elevation and Figure 2 a sectional plan view on the line A B of Figure 1 of a gas producer with a grate constructed and arranged in one convenient form in accordance with this invention.

Figure 3 is an end view of the grate.

Figure 4 is a part sectional elevation of a bar of the grate drawn to a larger scale.

Figure 5 is a plan view of the bar shown in Figure 4:.

Figure 6 is a sectional end view of a bar of V the grate on the line C D of Figure 4.

The same reference letters in the difierent views indicate thesame parts.

The producer grate comprises a plurality of bars a parallel with one another and pivotally mounted in position with means for turning or oscillating them simultaneously about their pivots so that they move in unison. The upper surface of each bar. is curved or a part of a cylinder as shown in Figures 3 and 6 and relatively long or deep slots 0 spaced a short distance apart extend inwards from the opposite edges of the curved face. The slots in one bar come opposite the unslotted portions of the adjacent bars as shown in Figure 2. The pivotal support of each bar is provided by detachable trunnion like parts (Z which are carried in bearing blocks 6 on side members 6 The trunnions are heldin position by plates 7 which enter slots therein and are secured to the parts a. By removing said plates f the trunnions can be withdrawn to allow of the ready removal of the bars for inspection or renewal purposes.

The oscillation of the bars may be effected from a crank g and connecting'rod it through a rod 71 having slots therein, into which enter projecting lugs or crank pin like parts upon the respective bars. The movements of the bars in unison effect, due to the shape of the bars, an efiectual clearing of the same of clinker and the like which is pinched between adjacent bar edges as one side of one bar asof the next bar bars are oscillated may be either above or below the bar pivots b.

The grate is of rectangular form and the water jacketed producer casing p of cylindrical form. A feed hopper Q with a rotary valve or like closure at its upper end is disposed centrally above theproducer chamber, the delivery from said hopper being by way of a central feed pipe 1 with a mouthpiece s at its lower end which is closed by the fuel in the producer so that as the level of the coke or fuel falls due to the producer action, a further feed from the hopper to the fuel bed takes place automatically. 'A uniform thickness of fuel is thus obtained in the producer, which ensures the production of uniform quality of gas.

What we claim 1s A. gas producer grate comprising a plur'ality of bars producing a grate of rectangular form below a cylindrical producer casing, the'bars each having their upper surface of curved form with relatively long or deep slots spaced a short distance apart and extending inwards from the opposite edges of the curved face, the slots in one barcoming opposite the unslotted portions of adjacent bars, removable trunnions inserted at both ends of the said bars bearin blocks for said trunnions, plate members constructed and arranged to enter slots provided in the said trunnions and to be secured to saidbearing blocks so as to lock the trunnions in position, projecting lugs or crank pin like parts on the bars which lugs engage within slots pro-' vided in a rod which is reciprocated through the medium of a connecting rod and crank to oscillate the bars in unison, spaces being provided in the latter to which water or a steam is fed, and nozzles at opposite sides of each bar for the delivery of steam around the bar. 7

In testimony whereof We have signed our names to this specification. V
